<p>A torque-proportioning differential of the helical pinion type includes a housing having a body section to one end of which is removably connected a cover section, the one body section end being machined to define a central longitudinal bore and a plurality of circumferentially spaced pairs of longitudinal pinion cavities in longitudinal communication with each other and with the central bore, respectively. The pinion cavities of each pair are of unequal depth, thereby to receive corresponding longitudinally offset helical pinions, respectively. In order to maintain the pinion of the cavity of greater depth adjacent the bottom wall of the cavity, a hub extension is provided on the other end of that pinion which extends the length of the pinion for engagement at its free end with a thrust surface carried by the housing cover section. The depth of the other pinion cavity corresponds with the length of the pinion associated therewith, whereby that pinion is maintained in a position adjacent a thrust surface on the cover section. The cover section is piloted on the body section of the housing, thereby to assure proper alignment and concentricity, and to simplify assembly of the differential components.</p> |
